Description

Technical Field

[0002] PTFE membrane is a microporous film made of polytetrafluoroethylene dispersed resin through special processes such as premixing, extrusion, calendering, and biaxial stretching. It is divided into clothing membrane, Puwei waterproof membrane, filtration membrane, and purification membrane. The main purpose of PTFE membrane calendering is to increase its crystallinity through the calendering process, so that the molecules are oriented and closely arranged, thereby significantly improving the mechanical strength. This process not only reduces the porosity, but also enhances the physical properties of the film, making it perform well in a variety of applications.

[0003] The existing calendering machines can complete the calendering operation of PTFE membrane during use, but the distance between the calendering rollers of the existing calendering machines is mostly fixed. When the distance between the calendering rollers needs to be adjusted, the bolts on the outside of the calendering rollers need to be removed before adjustment. The adjustment process is relatively laborious and complicated. Therefore, a PTFE membrane calendering production equipment is proposed to solve the above-mentioned problems. Utility Model Content
